The Maximum Sum-Balaban Index of Tree Graph with Given Vertices and Maximum Degree

通过图的操作的方法,本文给出了给定顶点和最大度树图中,取得最大Sum-Balaban指标的极图。 In this paper, by using the graph operation, we determine the extremal graph which attains the maximum Sum-Balaban index among trees with given vertices and maximum degree.
